PETER BROADBOOKS, OF BATAVIA, NEW YORK.

PLIERS.

To all whom it may concern:

Be it known that 1. PETER BROADBOOKS, of Batavia,in the countyol Genesee and State of New York"; have invented certain new and useful Improvements in Pliers L and I hereby declare that the following is. a full, clear, and exact description thereof, reference being had to the accompanying drawings, nlllCil form part of this specification.

in .the construction of pincers and like tools wherein the jaws are hinged between side plates it is customary to form the said side plates with oilsets in order to throw the ends of the same into proper alinement, and such construction is objectionable for many purposes since the offset portions are not sufficiently rigid and have a tendency to yield w hen subjected to force.

The primary object of the present invention has accordingly been to design a simple and inexpensive tool of the above mentioned type in which the side plates can. not spring and which will operate etliciently under the most trying circumstances.

The invention further contemplates the provision of a pair of pliers in which one of the jaws carries a detachable blade of novel construction, the said blade being formed with interchangeable cutting edges.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of constructioin,

, reference is to be had to the following descrip- 'tion and accompanying drawings, in which:

Figure 1 is a front elevation of a pair of pliers embodying the invention, portions of the handles being broken away. Fig. .2 is a side view of the same. Fig. 3 is a front elevation, the side plates and one of the handles being removed. Fig. l is a detail view of one of the jaws. Fig. 5 is a similar view of the detachable cutting blade. Fig. 6 is a side view oi one of the companion members and shows a modification.

Corresponding and like parts are referred to in the following description and indicated on the accompanying drawing 'by like reference characters.

} Broadly speaking the invention is in the nature of a pair of pincers or pliers and comprises pivotelly connected companion membore; 1 and 2 formed with cooperating jaws and handles. ii-lore specifically describing the invention it will be observed that the member 2- is con- Specification of Letters Patent.

stituted by a handle 3 having one end thereof bifurcated, the opposite companion member 1 being received between the arms 4 of the bifurcation and the two members being pivotally connected by means of the pin 5, the said member 1 comprisinga handle 9 and r jaw 10 formed integrallyin one piece. The jaw 6 of the member 2 is separatelyiormed and is received between the extremities of the arms l of the bifurcation, being attached to the same by any suitable means such as the pin 7, and is formed with a shank 8 which is pivotally connected to the jaw 10 of the opposite companion member by means of the pin 5. This hinged connection may be brought about in any suitable manner such as in the present instance by halving theaws 6 and 10 together at the pivot point, the op with an approximately radially disposed shoulder 12 which-cooperates with a corresponding shoulder 13 upon the handle of the j aw 10 of the opposite complemented member 1 to produce the desired result. Under some conditions it may be found desirable to employ a gage screw such as indicated at 14 to prevent the cutting edges of the jaws from coming into contact with each other with undue force, the said gage screw being threaded through one of the handles and en gaging the opposite handle. By adjusting this gage screw 14 compensation may be readily made for wear as required.

The heads of the jaws are extended laterally in opposite'directions for the purpose of providing alarge working portion; .One of the jaws, and in the present instance the jaw 6, is provided with an integral cutting edge 15, while the opposite jaw 10 is formed with a recess 16, said recess terminating in an inclined shoulder 17. Fitting removably within this recess is a blade 18 which is held in position by means of the screws 19 and has 1 senses held in cooperative relation with the before I to limit the opening movement of the jaws,

mentioned integral cutting edge of the jaw 6, the opposite beveled edge bearing against the inclined shoulder 17. In this manner the blade 18, is locked in position and the cutting edge not in use is protected from in ury.

It is to be distinctly understood that I do not limit myself to the exact construction shown, as slight modifications could be made without departing from the spirit of the invention.

Having thus described the invention, what is claimed as new is:

1. The herein described pliers comprising a bifurcated member, and an opposed member having an integral jaw entered between the bifurcation of the first member/a pivot bolt transfixing said jaw and bifurcation, an

opposed separately formed jaw fastened to an between the ends of said bifurcation and pivoted on said bolt, said separate jaw artd the handle of the solid jaw having opposed radial surfaces adapted to limit the opening movement of the jaw, substantially as de scribed.

2. The herein described pliers composed of a handle having an integrally formed jaw, and also having an inclined shoulder adjacent the pivot point of the jaw; an opposed member comprising a handle having a ifurcation on its upper end, said bifurcation embracing the said jaw and projecting beyond the pivot oint; a bolt transfixing the said jaw and bifurcation, a separately formed jaw fastened to and between the ends of the bifurcation and having a shank pivoted on said bolt between the arms of the bifurcation and also having a shoulder adapted to engage the shoulder on the other handle substantially asdescribed.

3. The herein described pliers composed of a handle having an integrally formed jaw provided with a recess at its upper end, and a' removable reversible blade detachably secured in the said recess; an opposed member comprising a handle having a bifurcation on its upper end, said bifurcation embracing the aforesaid jaw and projecting beyond the pivot point; a bolt transfixing the bifurcation and said jaw; and a separately formed jaw fastened t0 and between the ends of the bifur: cation and having a shank ivoted on said bolt between the arms of the bifurcation.

4. The herein described pliers composed of a handle having an integrally formed jaw provided with a recess at its upper end, and

said handle having an inclined shoulder adjacent the pivot point of the jaw, a removable reversible blade detachably secured in said recess; an opposed membercomprising a handle having a bifurcation on its u per end, said bifurcation embracing the a oresaid jaw and projecting beyond the pivot point; a bolt transfixing the bifurcation on the jaw, and a separately formed jaw fastened to and between the ends of the bifurcation and having a shank ivoted on said.
